在ASP.NET用户注册过程中MemberShipException [英] MemberShipException during the User Register at ASP.NET

问题描述

我使用的是ASP.NET MVC 4模板来创建我的应用程序，在我的方法注册的帖子，我把那个叫用户配置并保存新的信息，在这种情况下，这将节省用户类型。

I'm using the ASP.NET MVC 4 template to create my application, in my method Register POST, i put a block that call the UserProfile and save new information, on this case, it will save UserType.

问题是：每一次，我会保存用户，异常 MembershipCreateUserException 被称为并显示在页面上的以下信息：
用户名已经存在。请输入不同的用户名。
用户保存在数据库中。

The problem is: Every time that I'll save the user, the exception MembershipCreateUserException is called and the following message is displayed on the page: User name already exists. Please enter a different user name. The User is saved on Database.

这是我的方法注册：

public ActionResult Register(RegisterModel model)
        {
            if (ModelState.IsValid)
            {
                // Attempt to register the user

                try
                {

                   // var user = new UserProfile() { UserName = model.UserName };

                    WebSecurity.CreateUserAndAccount(model.UserName, model.Password);
                    WebSecurity.Login(model.UserName, model.Password);
                    return RedirectToAction("Index", "Home");

                }
                catch (MembershipCreateUserException e)

                {
                    ModelState.AddModelError("", ErrorCodeToString(e.StatusCode));
                }
//new code
                using (UsersContext db = new UsersContext())
                {

                    // Insert name into the profile table
                    UserProfile newUser = db.UserProfiles.Add(new UserProfile { UserName = model.UserName, UserType = model.UserType });
                    db.SaveChanges();

                }
            }

任何人都知道如何解决呢？每一个帮助将是有效的！谢谢你们。

Anybody knows how can i resolve it? Every help will be valid! Thanks guys.

推荐答案

下面一行添加一个新用户：

The following line adds a new user:

WebSecurity.CreateUserAndAccount(model.UserName, model.Password);

和这条线又做的：

UserProfile newUser = db.UserProfiles.Add(new UserProfile { UserName = model.UserName, UserType = model.UserType });

而不是尝试下面添加用户类型创建用户时，确保用户等级和积分是你RegisterModel模型的一部分​​：

Try instead the following to add the user type when creating the user, make sure UserType is part of your RegisterModel model:

WebSecurity.CreateUserAndAccount(model.UserName, model.Password, new { UserType = model.UserType});

所以整个注册方法如下：

So the entire Register method will look like this:

public ActionResult Register(RegisterModel model)
        {
            if (ModelState.IsValid)
            {
                // Attempt to register the user

                try
                {
                   WebSecurity.CreateUserAndAccount(model.UserName, model.Password, new { UserType = model.UserType });

                   return RedirectToAction("Index", "Home");

                }
                catch (MembershipCreateUserException e)
                {
                    ModelState.AddModelError("", ErrorCodeToString(e.StatusCode));
                }
            }
